= gr-fosphor 

 GNU Radio block for RTSA-like spectrum visualization using GPU 

 http://git.osmocom.org/gr-fosphor/ 

 == Building 

 === GLFW3 

 Install dependencies 

 {{{ 
 sudo apt-get install cmake xorg-dev libglu1-mesa-dev 
 }}} 

 Build GLFW 

 {{{ 
 git clone https://github.com/glfw/glfw 
 cd glfw 
 mkdir build 
 cd build 
 cmake ../ -DBUILD_SHARED_LIBS=true 
 make 
 sudo make install 
 sudo ldconfig 
 }}} 

 === gr-fosphor 

 Install dependencies 

 ==== For NVidia 

  * install [http://www.nvidia.com/object/unix.html NVidia drivers] 

 {{{ 
 sudo apt-get install nvidia-opencl-dev opencl-headers 
 }}} 

 ==== For AMD 

  * install [http://support.amd.com/en-us/download AMD drivers] (13.4 and 13.11 beta6 drivers are known to work on linux) 
  * install [http://developer.amd.com/tools-and-sdks/heterogeneous-computing/amd-accelerated-parallel-processing-app-sdk/ AMD APP SDK] 

 ==== For Intel 

  * No OpenCL support on Linux for HD and Iris Graphics (Wake up, Intel!) 

 Build gr-fosphor 

 {{{ 
 git clone git://git.osmocom.org/gr-fosphor 
 cd gr-fosphor 
 mkdir build 
 cd build 
 cmake .. 
 make 
 sudo make install 
 sudo ldconfig 
 }}} 

 Build benchmark tool 

 {{{ 
 cd gr-fosphor/lib/fosphor 
 make 
 }}} 

 Fosphor is known to build successfully on Linux, OSX and Windows.

 == Bandwidth figures 

 There's a benchmark program available which allows to estimate the maximal bandwidth that can be processed with a specific GPU. 

 To build it: 

 {{{ 
 cd gr-fosphor/lib/fosphor 
 make 
 }}} 

 Then execute it by providing a prerecorded complex float file (a couple of 100MB should be fine) in gnuradio format. 

 {{{ 
 ./main some.cfile 
 }}} 

 Try to leave the window to its default size if possible and watch out for the Msps numbers printed out to the console. 

 Submit your numbers & help us to create a GPU survey. We are especially interested in the top end and mobile graphics figures.
